no, not really. command arguments are always strings.

If you want to use a int var then you could do this:

int n = 500;
p = r.exec(new String[] {"cmd.exe", "/k", "start", "c:\\a\\test.exe", Integer.toString(n)}, null, new File("c:/a"));

objects.... it works...
one question i may need to pass more than one.... could i just add it to Integer.toString as:
int n = 500;
int x = 120;
p = r.exec(new String[] {"cmd.exe", "/k", "start", "c:\\a\\test.exe", Integer.toString(n, x)}, null, new File("c:/a"));
thanks ....

depends how it is expecting the vars, if its expecting two numbers then try:

p = r.exec(new String[] {"cmd.exe", "/k", "start", "c:\\a\\test.exe", Integer.toString(n), Integer.toString(x)}, null, new File("c:/a"));
